Find and Fix It Guide: Elective deferrals Weren’t Limited to the Amounts under IRC Section 402(g)



MISTAKE: Elective deferrals weren’t limited to the amounts under IRC Section 402(g) for the calendar year and excess deferrals weren’t distributed
Find the Mistake Fix the Mistake Avoid the Mistake
Inspect deferral amounts for plan participants to ensure that the employee hasn’t exceeded the limits  Distribute excess deferrals. Review the ComplianceDashboard information on running a compliant plan.  Work with plan administrators to ensure that they have sufficient payroll information to verify the deferral limitations of IRC Section 402(g) were satisfied.


Internal Revenue Code Section 402(g) limits the amount of elective deferrals a plan participant may exclude from taxable income each calendar year. IRC Section 401(a)(30) provides that, for a plan to be qualified, it must provide that the amount of elective deferrals for each participant under all plans of the same employer not exceed the 402(g) limits. The limit on elective deferrals under Section 402(g) is:

Limits on the amount of elective deferrals a plan participant may contribute to a SIMPLE 401(k) plan are different than those in a traditional or safe harbor 401(k) plan.

Catch-up contributions: A plan may permit participants age 50 or over at the end of the calendar year to make additional deferrals. These additional contributions are called catch-up contributions and these aren’t subject to the general limits that apply to 401(k) plans (see IRC Section 414(v)). An employer isn’t required to provide for catch-up contributions. However, if your plan allows catch-up contributions, you must allow all eligible participants to make catch-up contributions.

Catch-up contributions are not subject to the Section 401(a)(30) plan qualification rule.

Elective deferrals include both pre-tax deferrals and designated Roth contributions. Generally, you must consider all elective deferrals made by a participant to all plans in which the employee participates to determine if the employee has exceeded the 402(g) limits. If an employee has elective deferrals in excess of the 402(g) limit under one or more plans of an employer, each plan is subject to disqualification.

Your plan document may impose its own lower limit on the deferral amount or on the percentage of pay that participants may defer. Additionally, your plan may need to limit a plan participant’s elective deferrals to meet certain nondiscrimination requirements.

If the total of a plan participant’s elective deferrals exceeds the limit under IRC Section 402(g), to avoid failing IRC Section 401(a)(30), the excess amount plus allocable earnings must be distributed to the participant by April 15 of the year following the year of deferral. Excess deferrals not timely returned to the participant are subject to additional tax.

Timely withdrawal of excess contributions by April 15

Consequences of a late distribution

Excess deferrals distributed to highly compensated employees are included in the ADP test in the year the amounts were deferred. Excess deferrals distributed to nonhighly compensated employees aren’t included in the ADP test if all deferrals were made with one employer. Excess deferrals distributed after April 15 are included in annual additions for the year deferred.

How to find the mistake:

Ensure that no one’s elective deferrals exceed the 402(g) limit for a year by comparing the amount deferred to the 402(g) limit. If anyone exceeds the 402(g) limit and this isn’t corrected, the plan could be disqualified.

How to fix the mistake:

IRC Section 72(t) imposes a 10% additional tax for distributions that don’t meet an exception, such as death, disability or attainment of age 59 ½, among others. To avoid this additional tax, correct excess deferrals no later than April 15 of the following year. If you don’t correct by April 15, you may still correct this mistake under EPCRS; however, it won’t relieve any Section 72(t) tax resulting from the mistake.

Under Revenue Procedure 2021-30, Appendix A, section .04, the permitted correction method is to distribute the excess deferral to the employee and to report the amount as taxable both in the year of deferral and in the year distributed. These amounts are reported on Form 1099-R.

Employer X maintains a 401(k) plan that has 21 participants. For calendar year 2018, Ann deferred $19,500 to the plan. Ann is under age 50 and isn’t eligible to make catch-up contributions. Ann has excess deferrals of $1,000 because $18,500 is the 402(g) maximum amount permitted for 2018. Employer X didn’t discover this mistake until after April 15, 2019. On November 1, 2019, X distributed the excess deferral (plus earnings of $100, totaling $1,100) to Ann.

For 2018 (year of deferral), Ann must include $1,000 in gross income. For 2019 (year of distribution), Ann must include $1,100 in gross income. Employer X would report this amount on Form 1099-R. In addition, Ann must pay the additional 10% early distribution tax under IRC Section 72(t).

Correction programs available:

Self-Correction Program:
The example shows an operational problem because Employer X failed to follow the plan terms prohibiting any employee’s elective deferrals from exceeding the 401(a)(30) limit. If the other eligibility requirements of SCP are satisfied, Employer X may use SCP to correct the failure.

Voluntary Correction Program:
Correction is the same as under SCP. Employer X makes a VCP submission per Revenue Procedure 2021-30. The fee for the VCP submission is based on the amount of the plan assets (as reported on the most recently filed Form 5500), ranging from $1,500 to $3,500. When making its VCP submission, Employer X must include Forms 8950 and 8951 and Form 14568, “Model VCP Compliance Statement,” along with Forms 14568-A through 14568-I, “Schedules.” These must be submitted electronically in PDF format.

Audit Closing Agreement Program:
Under Audit CAP, correction is the same as under SCP. Employer X and the IRS enter into a closing agreement outlining the corrective action and negotiate a sanction based on the maximum payment amount.
